We got a chance to help beta test Mailbox before it is publicly available later this year. Starting today, you can sign up for the Mailbox reservation system.

Mailbox

Here's how it works:

Once you head to the website and sign up, you'll secure your place in line.

Mailbox will send you a text message with your reservation number, which is your place in line.

Along with the reservation number you'll also receive a private code, which you'll need to claim your reservation when the app is ready for download.

Reservations will be filled on a first-come, first-served basis. There's no word yet on when Mailbox will be available for everyone. The good news: It'll be free.

Mailbox is one of the best productivity/email management apps we've ever come across. The app is based in simplicity and supports gestures that delete a message, archive it, or remind you to read it later.

If you're worried about privacy and security, Mailbox says the company has gone through a lot of trouble to encrypt messages and ensure its team cannot read your emails.
